Amarali inhabit two countries in South America. Referenced by many in herpetoculture as the Short-tail boas.

Bolivian Amarali in the United States can all trace their origin back to Joe Terry. There are 4 original lines, the '86, '87, '89 and Silverback. In crossing the '86 x '89 lines some beautiful colored boas were produced that were named Orange Crush. With these 5 groups breeders have mixed and selectively bred for some incredible boas.
South Brazilian amarali in the U.S. come from two lines, the Lloyde Lemke and Kerry King lines. True South Brazilian Amarali are much rarer than their Bolivian counterparts in the United States and the King line by far the hardest to obtain.
